Then again, for a stable -> current upgrade it might be needed in stable as well one could argue. Also, the libc sources don't have to be screwed up for libc to be trashed. Kernel panics at inopportune times due to other bugs can result in pain. > b) I've not seen the numbers for this.

I would only argue for a static make on teh basis of recoverability from bad juju, not for speed. > Warner -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
